Patent DE-4230384-A1 (DE)
Title: Dewatering press for compacting wet sludge from e.g. paper recovery process - has cantilevered feed screw mounted on self-aligning bearings allowing screw to swivel under radial forces and thereby relieve working parts of heavy loads.
Inventor: SCHNELL HANS
IPC: B30B9/02
Filed: 1992-09-11
Abstract: The press consists of a perforated stationary drum (4) along which the wet sludge is transported and progressively compressed by the action of a cantilevered feed screw (3). The bearings (16,17) are of the self-aligning type and allow the screw to swivel like a rotating pendulum about a point (D) on its axis, depending on the resultant of radial forces acting on the screw. As a consequence the sludge is uniformly squeezed dry and the press working parts are relieved of heavy loads. The screw drive unit (12) has a torque arm allowing the reaction torque of the screw drive to be supported without constraining the swivelling movement of the screw. USE/ADVANTAGE - Simple, accessible design of wet sludge dewatering press used in paper recovery process. It operates with reduced wear of working parts and has high compacting efficiency.

Patent DE-4327183-A1 (DE)
Inventor: MEISNER EBERHARD DR
IPC: H01M50/541
Filed: 1993-08-13
Abstract: In the case of a novel storage battery (accumulator), there are two current busbars, which collect the surge-arresting lugs of the electrodes and are usually arranged symmetrically with respect to one another near to the edges of the plate pack. That current busbar having the one polarity is located above the centre of the plate pack and that current busbar having the other polarity is located alongside the former. The central position is particularly favourable for the current discharge from an electrode or cell, for which reason this current busbar should be connected to that electrode polarity which is less capable in respect of its electrical conductivity (for example the positive PbO2 electrode in the case of the lead-acid battery). <IMAGE>

Title: Process for producing high-purity, stress-free inter-fractional metal coatings or shaped articles
Inventor: FORREST DAVID
IPC: C23C16/01
Filed: 1993-10-06
Abstract: The process describes the production of high-purity, inter-fractional metal coatings on various ceramic substrate materials such as boron nitride or carbon, wherein an appropriate process procedure gives either an adherent coating or else free-standing, thin-walled shaped articles which can be separated from the mandrel after CVD coating. The significant advantage is that free-standing shaped articles which are dimensionally stable, even at high temperatures, can be produced using this technology, without complicated machining becoming necessary. The layers produced by the process are free of pores both in the case of coatings and in the case of free-standing shaped articles.
